Big Guy the Stilted is a giant robotic Shy Guy on Stilts operated by multiple Shy Guys in Yoshi's Island DS. He is the boss of his castle, residing there along with many Shy Guys. To defeat him, Yoshi must use eggs (or Baby Bowser's fire breath) to knock Big Guy the Stilted off the edge of the platform they are fighting on, which is surrounded by lava, giving the Yoshi a chance to Ground Pound him. Many Shy Guys are inside this robot, jumping out occasionally making for an easy egg supply. After three Ground Pounds, it cracks, exposing all of the Shy Guy operators, after which it falls into the lava.
